Distribution. China: Heilongjiang, Jilin, Liaoning. Nanjing, Shanghai, Zhejiang; Taiwan; Vietnam; Laos; Korea; Japan: Tokara Isls. (Nakano-shima), Okinawa-jima, Ishigaki-jima, Iriomote-jima.

Remarks. This is the first record of this species from Japan. The body size of the specimens collected from the low-latitude area (e.g. Taiwan, Vietnam, and Japan) is somewhat larger than those from the high-latitude area (e. g. China and Korea).
